Ⅰ. Product Introduction of Mercedes Benz 274 water pump
How dose Mercedes Benz 274 water pump work?
The engine drives the water pump bearing and impeller to rotate through the pulley. The impeller drives the cooling liquid in the water pump to rotate together. It is thrown to the edge of the water pump housing under centrifugal force, and a certain pressure is generated at the same time, and then it flows out from the water outlet or water pipe. The pressure at the center of the impeller is reduced due to the cooling liquid being thrown out. The cooling liquid in the water tank is sucked into the impeller through the water pipe under the pressure difference between the inlet of the water pump and the center of the impeller to realize the reciprocating circulation of the cooling liquid.
The bearings supporting the water pump shaft are lubricated with grease. Therefore, it is necessary to prevent the coolant from leaking into the oil to cause the fat to emulsify, and at the same time to avoid the leakage of the grease. The sealing measures of the water pump to prevent leakage include water seals and gaskets. The water seal dynamic seal ring and the shaft are installed through an interference fit between the impeller and the bearing. The water seal static seal seat is tightly press-fitted on the housing of the water pump to achieve the purpose of sealing the coolant.
The water pump housing is connected to the engine through a gasket and supports moving parts such as bearings. There is also a drain hole on the water pump housing, which is located between the water seal and the direction. Once the coolant leaks through the water seal, it can be discharged from the drain hole to prevent the coolant from entering the bearing cavity, destroying the bearing lubrication, and causing the parts to rust. If the coolant still leaks after the engine is stopped, it indicates that the water seal has been damaged.
